Two researchers have discovered that bumblebees can fly high at elevations of 29,527 feet. That is higher than Mount Everest! Michael Dillon and Robert Dudley worked with bumblebees native to Sichuan, China, that live at elevations over 10,000 feet. The question is how these bumblebees do that with the thin air and reduced oxygen levels at such altitudes.
The researchers used a pressure chamber to simulate high-altitude conditions. Using high-speed cameras, the researchers saw that the bumblebees didn’t change their wings’ flapping but rather used deeper arcs to scoop more air with each beat. This technique also enables more efficient escapes from predators and the ability to carry heavy nectar loads.
Bumblebees can fly high, but how they can sustain their metabolism with so little oxygen remains unanswered. We have much to learn from bumblebees, but their design challenges all observers. The writer of Proverbs said, “Go to the ant; consider her ways and be wise.” (Proverbs 6:6). All of God’s creatures have something to teach us, including ants and bumblebees.
